NieR Replicant stores its Steam PC data beneath a user-ID directory, which is useful because it keeps different Steam accounts separated but also makes casual copy/paste mistakes easier. Community troubleshooting shows that persistent completion state can survive in shared game-data files, so a single character slot is not a complete backup strategy. SaveEditor recommends copying the whole user-ID directory, keeping Steam Cloud state in mind, and restoring files from the same snapshot rather than mixing a new slot with old global data.
Identify the exact save you intend to edit
The researched NieR Replicant ver.1.22474487139… PC save location is Windows: %USERPROFILE%DocumentsMy GamesNieR Replicant ver.1.22474487139Steam<user-id>. Known file/folder pattern: Game and system data are stored inside the Steam-user-specific save directory; community reports commonly reference GAMEDATA among the persistent files.. Storefront context: Steam. The save directory is Steam-account-specific. Do not merge files from different user-ID folders without keeping a known-good copy of each set. Do not edit a similarly named file from a different profile, edition, or cloud cache.
Make an untouched backup first
Close the game and Steam synchronization, then copy the entire user-ID directory. Keep a dated untouched copy before experimenting with GAMEDATA or individual slot files. Keep that copy outside the live save directory and do not overwrite it with later experiments. Cloud context: Steam Cloud can re-download deleted or replaced files when synchronization is enabled. If a launcher can synchronize the save, prevent it from silently replacing either the original or edited copy while testing.
Understand the format boundary
The remaster stores PC progress under a Steam user ID directory in Documents. Some persistent state can remain outside the currently selected character slot, so folder-level backup is safer than removing one file. File-extension context: No single extension is sufficient to identify every relevant save record. Compatibility note: Persistent completion/system state may be stored alongside character saves. Deleting a file to reset one behavior can have broader consequences and cloud sync may restore it. These facts help identify the save but do not automatically reveal every field, checksum, encryption rule, or version-specific structure inside it.
Use only a Tool whose claim matches the file
Generic viewers and diff tools can inspect bytes without claiming game-specific semantics. A game-specific editor should be used only when its Tool page explicitly lists NieR Replicant ver.1.22474487139…, a matching supported version/container, and a Verified operational runtime. A planned URL or Game Hub is not evidence that an editor exists.
Test the edited copy safely
Write to a new output file when the Tool supports it, keep the original backup, restore the edited copy into the correct profile/storefront location, and launch the game only after the file operation finishes. If the game rejects it, If deleted data reappears, check Steam Cloud. If a save is reported corrupt after a manual replacement, restore the full matching backup set instead of mixing files from different dates. Return to the untouched backup before trying another change.
